A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
Utilities listed in POSIX.1-2017. This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS).
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems.. GNU Core Utilities include basic file, shell and text manipulation utilities.
A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such program is often the first written by a student of a new programming language, [ 1 ] but such a program can also be used as a sanity check to ensure that the computer software intended to compile or run source ...
The keywords, syntax, dynamically scoped variables, and other basic features of the language are all copied from the Bourne shell, sh. Other features, e.g., history, are copied from the C shell, csh, and the Korn Shell, ksh. It is a POSIX-compliant shell with extensions.
Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. Most Linux distributions , as collections of software based around the Linux kernel and often around a package management system , provide complete LAMP setups through their packages.
